Stay up to date on the latest science with Brush Up Summaries. This article was updated on March 24th, 2023. Each cell in an organism has an average life span. For example, cells lining the surface of ...

Researchers discovered that a protein called AP2A1 acts as a master switch controlling whether cells behave young or old When scientists reduced AP2A1 levels in aged cells, they showed signs of ...

Aging is a complex biological process characterized by the progressive decline of physiological integrity, leading to impaired function and increased vulnerability to disease. It is the strongest risk ...

A new study reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence -- when a cell loses the ability to grow and divide. The researchers ...

As the brain ages, many cell types succumb to senescence. How does this start? In the September 10 Nature Aging, scientists led by Wei Cai, Zhengqi Lu, and Quentin Liu at Sun Yat-Sen University, ...

A group of Kobe University researchers have revealed that adding Vitamin B 2 to cells that have been exposed to aging stress increases the mitochondria’s ability to produce energy and prevents cell ...

When cells are exposed to stress and damage, cellular senescence occurs. This phenomenon increases with aging. Senescent cells (SnCs) attain permanent growth arrest and exhibit senescence-associated ...

Eventually, aging comes for us all — but new evidence suggests that in key ways, it may be a contagious condition. In a provocative new study published in the journal Metabolism, scientists from South ...
